Long-Term Echocardiographic and Clinical Outcomes After Invasive and Non-Invasive Therapies for Sub-Massive and Massive Acute Pulmonary Embolism - 28/06/24
Abstract |
Aim |
Acute pulmonary embolism (PE) is a significant cause of mortality in the hospital setting. The objective of this study was to outline the long-term outcomes after surgical and non-surgical management for patients with massive and submassive PE.
Methods |
Population cohort observational study evaluating all patients who presented to three tertiary hospitals in the state of Western Australia with access to cardiothoracic services over 5 years (2013–2018). Reviewed notes of all patients as well as radiology, linked mortality data and all available echocardiography studies at the primary hospital.
Results |
In total, 245 patients were identified, of which 41 received surgical management and 204 non-surgical management; demographic data was similar. Clinically, the surgical group had higher rates of shock requiring vasopressors, severe bradycardia, or cardiopulmonary resuscitation prior to intervention. The 28-day mortality was not statistically significantly different between the surgical embolectomy group (2/41 [4.2%]) and the non-surgical group (17/201 [8.3%]) (p=0.382). There was no difference in 12-month mortality, including when this was adjusted for vasopressors, right ventricular (RV) strain, troponin, and brain natriuretic peptide. In the massive PE sub-group, 28-day mortality was not significantly different: 2/29 (6.9%) surgical group vs 7/34 (20.2%) non-surgical group (p=0.064). Higher rates of severe RV impairment and dilatation were present in the surgical group. All patients with available echocardiography studies at outpatient follow-up returned to normal or mild RV impairment.
Conclusion |
Patients who presented with massive or submassive PE had similar outcomes whether treated with surgical or non-surgical management. Surgical embolectomy is a safe option in a cardiothoracic centre setting.
